Mexico Initiates Antidumping Duty Investigation into Hollow Aluminum Profiles from the United States and China

Mexico Initiates Antidumping Duty Investigation into Hollow Aluminum Profiles from the United States and China  

On March 5, 2025, Mexico’s International Trade Practices Unit (UPCI) initiated an antidumping duty (AD) investigation into imports of hollow aluminum profiles from the United States and China. If an affirmative decision is issued in this investigation, duties may be imposed on subject U.S. exports.  

What is an antidumping duty (AD) investigation?  

An AD investigation assesses whether foreign goods imported into a country are being sold at less than fair value (below prices or costs) in the domestic market (i.e., being dumped) and whether this is causing or threatening to cause injury to the domestic industry.  

How can I participate?  

U.S. companies involved in the production, sale, or distribution of the subject goods should register as interested parties as soon as possible. Registration is the first step in protecting your rights in a foreign trade remedy proceeding. Doing so allows you to access the case records and submit information and comments, ensuring that your views are considered. Please follow the instructions listed in paragraphs 227 and 228 of the Initiation Notice to register as interested party in this proceeding.
